+/* ------------------- Fine Control over USB Descriptors ------------------- */
+/* If you don't want to use the driver's default USB descriptors, you can
+ * provide our own. These can be provided as (1) fixed length static data in
+ * flash memory, (2) fixed length static data in RAM or (3) dynamically at
+ * runtime in the function usbFunctionDescriptor(). See usbdrv.h for more
+ * information about this function.
+ * Descriptor handling is configured through the descriptor's properties. If
+ * no properties are defined or if they are 0, the default descriptor is used.
+ * Possible properties are:
+ *   + USB_PROP_IS_DYNAMIC: The data for the descriptor should be fetched
+ *     at runtime via usbFunctionDescriptor().
+ *   + USB_PROP_IS_RAM: The data returned by usbFunctionDescriptor() or found
+ *     in static memory is in RAM, not in flash memory.
+ *   + USB_PROP_LENGTH(len): If the data is in static memory (RAM or flash),
+ *     the driver must know the descriptor's length. The descriptor itself is
+ *     found at the address of a well known identifier (see below).
+ * List of static descriptor names (must be declared PROGMEM if in flash):
+ *   char usbDescriptorDevice[];
+ *   char usbDescriptorConfiguration[];
+ *   char usbDescriptorHidReport[];
+ *   char usbDescriptorString0[];
+ *   int usbDescriptorStringVendor[];
+ *   int usbDescriptorStringDevice[];
+ *   int usbDescriptorStringSerialNumber[];
+ * Other descriptors can't be provided statically, they must be provided
+ * dynamically at runtime.
+ *
+ * Descriptor properties are or-ed or added together, e.g.:
+ * #define USB_CFG_DESCR_PROPS_DEVICE   (USB_PROP_IS_RAM | USB_PROP_LENGTH(18))
+ *
+ * The following descriptors are defined:
+ *   USB_CFG_DESCR_PROPS_DEVICE
+ *   USB_CFG_DESCR_PROPS_CONFIGURATION
+ *   USB_CFG_DESCR_PROPS_STRINGS
